Application filed August as, 1,924. Serial No. 734,267.

This invention relates to a bushing sleeve or shim for the ball casingand socket which" crosswise, so that it can be slipped over the shaft orhousing and up around the ball oint.

3 The invention has for its object the provision of a shim for the ballcasing and socket enclosing-a universal joint, which can be readilyinserted at a minimum expenditure of time, obviatingthe necessity ofpulling down the transmission and installing new transmission parts. Afurther object is the provision of a bushing sleeve or shim which willbe held in proper position at all times, which will act as a closure forthe joint between the flanges of the ball casing and socket to confinethe lubricant, and which will efiectual-ly compensate for wear betweenthe parts.

Other objects and advantages of the invention will hereinafter appear inthe following description and the novel features thereof will'beparticularly pointed out in the appended claim.

Like reference characters indicate like parts throughout the severalfigures of the drawing, in which- Figure 1 is a longitudinal sectionthrough that portion of an automobile transmission which includes theuniversal joint.

Figure 2 is a perspective, of the bushing sleeve or shim, and

Figure 3 is a section through a portion of the same showing the inwardburr or flange by means of which the shim is held in proper positionuponfthe ball of the joint.-

The numeral 10 indicates the rear portion of a gear case of -anautomobile transmission terminating in the socket section 11. The socketof a universal joint is formed by two parts being provided withoutwardly projecting flanges 11 and 12, by means of which the are firmlysecured to each other through t e medium of bolts. Between the '2 of thedrawing.

two flanges is a packing ring 13 of cork other suitable material.

Within the socket just described a ball shaped casing 14 is adapted tomove in a universal manner. The ball casing is provided with a sleeve 15mounted upon the Y torque shaft tube vehicleit will be appreciated thatthe ball 16. In the travel of the shaped casing 14: will move freelywithin the socket formed by the members 11 and 12, and that these partswill Wear and the joint between'them will become loose, resulting in acertain amount of rattle or noise, and if continued, resulting in damageto other parts of the transmission due to end thrusts permitted by thewear of this joint; To overcome these disadvantages, the bushing sleeveor shim of this invention has been devised. The shim is shown inperspective in Figure It is made of hard steel being stamped to conformin shape to a section'of the outer surface of the ball casing. It issplit in order to permit its easy insertion around the sleeve 15, and itis provided with an aperture 17 formed with a depending flange or burr18, which takes into an aperture of similar size in the ball casing.

When it is desired to insert the bushing or shim within the joint, thebolts passing through the flanges 11 and 12 are removed and the collar12 and cork washer 13 are movedbackward into the dotted line positionsshown in Figure 1. The shim, being split, can then be placed upon thesleeve 15 between the ball casing and the washer. it is then brought upto the ball casing and made to fit the same snugly with the flange 18lying within the aperture in the ball casing. In this -position theforward edge of the'shim will "move under the cork washer and into thesocket portion 11 and will thus act to take up wear between the ball casng andboth sections of the socket and will also tion and the boltsreinserted through the flanges 11 and 12 When the vehicle is at rest orstationary, the aperture 17 will be directly beneath the lower end ofthe grease cup 20-carried by the collar 12. may be forced from the cupthrough the ap- The grease erture 17 into the ball casing for the properlubrication of the universal joint.

It would be appreciated that by my invention a bushing or shim isprovided which will take up the Wear upon the joint between toaccomplish these functions will be efv fected.

Having described my invention what I claim as new and desire to secureby- Letters Patent is A bushing or shim for taking up the wear between aball casing and its socket of a universal joint, in which the casing andsocket 1 have aligned grease openings, consisting of a strip of metalhaving a shape conforming to a section of the outer surface of a ballcasing and provided with an aperture surrounded by a depending flange tofit within the grease aperture of the ball casing and maintaining theshim stationary with respect to the ball casing during the relativemovements of the casing and'socket In testimony whereof I aflix mysignature.
